对于自动变速箱的电磁阀有时候我们显得束手无策，因为我们没有鉴定它好坏的标准，有时候因为它引起的故障时有时无，经常使我们感到困惑。下面济南自动变速箱维修人员为您解析：

Sometimes we feel helpless about the solenoid valve of an automatic transmission because we do not have a standard for evaluating its quality. Sometimes, the faults caused by it are sporadic and often confuse us. Below, Jinan automatic transmission maintenance personnel will analyze for you:

小编认为对于电磁阀我们应该把它看作是喷油嘴的另一种工作方式，因为喷油嘴和电磁阀所发生的故障不外乎堵塞和滴漏。

The editor believes that for solenoid valves, we should consider them as another way of working for fuel injectors, because the faults that occur with the fuel injectors and solenoid valves are nothing more than blockage and dripping.

但是喷油嘴造成的结果我们可以通过分析发动机的短期和长期燃油调整值来加以确定。如果长期燃油调整超过百分之＋10，就表示油泵油压过低或喷油嘴堵塞。

However, the results caused by the fuel injectors can be determined by analyzing the short-term and long-term fuel adjustment values of the engine. If the long-term fuel adjustment exceeds+10%, it indicates that the oil pump pressure is too low or the fuel injection nozzle is blocked.

如果如果怠速时短期燃油调整超过百分之－10，则表示油泵油压过高或个别喷油嘴泄漏。喷油嘴对应发动机电脑的相应控制精度应该小于0.01毫秒。

If the short-term fuel adjustment during idle exceeds -10%, it indicates that the oil pump pressure is too high or individual fuel injectors are leaking. The corresponding control accuracy of the engine computer corresponding to the fuel injector should be less than 0.01 milliseconds.

虽然我们不能像对待喷油嘴那样的判断出故障的原因，我也不知道变速箱电脑相应电磁阀的控制精度是否比喷油嘴高（应该是电磁阀要比喷油嘴的控制精度低，因为换档过程是以秒为单位计算的，占空比电磁阀的控制频率一般是60HZ），但是我们开的是一样的，使用超声波清洗机清洗40分钟。因为造成故障的原因是相同的：

Although we can't judge the cause of the fault as we do with the fuel injection nozzle, I don't know whether the control accuracy of the corresponding solenoid valve of the transmission computer is higher than that of the fuel injection nozzle (it should be that the control accuracy of the solenoid valve is lower than that of the fuel injection nozzle, because the shift process is calculated in seconds, and the control frequency of the duty cycle solenoid valve is generally 60HZ), but we open the same, use the Ultrasonic cleaning to clean for 40 minutes. Because the causes of the malfunction are the same:

都是被磨损并污染造成的，所以相同。01N电磁阀因为结构所至，不光存在污染，有可能还有球阀的磨损，所以清洗之后要用其它方法做进一步鉴定。01V的电磁阀则是存在于电磁阀内部的磨损杂质很难去除，所以我们使用汽油作为清洗剂，并且清洗40分钟以上。

They are all caused by wear and pollution, so they are the same. Due to its structure, the 01N solenoid valve is not only contaminated, but may also have wear on the ball valve. Therefore, after cleaning, other methods should be used for further identification. The 01V solenoid valve is difficult to remove wear impurities that exist inside the solenoid valve, so we use gasoline as a cleaning agent and clean it for more than 40 minutes.

不管什么型号的变速箱须把电磁阀清洗的干净，使用手工方法是很难做到的。值得注意的是要使用频率40KHZ左右的超声波清洗，使用频率20KHZ或更低的超声波容易造成电磁阀内部的损坏。还有什么事项就来我们网站http://www.jnbsx.com咨询！

No matter what model of gearbox, it is difficult to clean the solenoid valve manually. It is worth noting that ultrasonic cleaning with a frequency of around 40KHZ should be used, as using ultrasonic waves with a frequency of 20KHZ or lower can easily cause damage to the interior of the solenoid valve.
